How to create a hybrid straight/curved section boundary using svg or css?

For my application, I'm creating a registration page with non-standard section boundaries. You can see what I'm trying to achieve here: it's not a simple arc - it has two straight lines, and an arc in between. As far as I know, the best way to achieve something like this is to use SVG. The problem is, the white area will have an image covering the entire area. For demonstration purposes I will use light blue.

Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records.

Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
